What happens if Nibe Water Heater shows sensor fault BT2?
- CConnie MooreJul 27, 2025
If your Nibe Water Heater shows a sensor fault BT2, it means the heating medium supply sensor is either not connected or defective. The system will then use BT3 if it's available. If BT3 isn't available, BT63 will be used instead.
